We used an analytical color fluorescence electron microscope to observe cathodoluminescence (CL) in the corpus luteum of rat. CL was emitted from lipid droplets and has a typical spectrum of two peaks at wavelengths of 320 and 430 nm. The

Previous studies have shown that endotoxin (lipopolysaccharide [LPS])-induced death can be prevented by preincubating LPS with lipoproteins in vitro or by infusing large quantities of lipids into animals prior to LPS administration. In the present study we determined whether physiological
The aim of this study was to gain insight into the effects of 4-aminopyrazolo(3,4-d)pyrimidine (4-APP), a hypocholesterolemic drug, on the adrenal cortex of the hamster, representing an animal species in which steroidogenesis primarily relies on utilization of cholesterol synthesized de

Prolonged (7-day) hCG infusion caused a remarkable hypertrophy of rat Leydig cells, coupled with a notable enhancement of their basal and stimulated testosterone production in vitro. It also provoked a conspicuous accumulation of lipid droplets in the cytoplasm of hypertrophic
Reactive oxygen species, such as superoxide, hydrogen peroxide, and lipid peroxides, impair luteal function. Vitamin E, a lipophilic antioxidant vitamin, provides a major avenue of protection by scavenging free radicals and terminating lipid peroxidation. We previously showed that ovarian vitamin
